2018-07-17soc: imx6qp: Use GENPD_FLAG_ALWAYS_ON for PU errataLeonard Crestez
This is functionally identical but simpler and slightly faster. The PU domain is turned on at boot time and never turned off. In the current implementation the pm core will repeatedly call power_off when the domain is unused and get -EBUSY back. If the domain is marked as "always on" instead the pm core won't even attempt to turn it off. In theory on 6qp it is safe to turn PU off in suspend, however that is best accomplished with a new core flag.

But the bulk of it is the treewide conversions to use either the 2-factor argument allocators (e.g. kmalloc(a * b, ...) into kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a * b) into vmalloc(array_size(a, b)). Coccinelle was fighting me on several fronts, so I've done a bunch of manual whitespace updates in the patches as well.

2018-06-12treewide: Use array_size() in vzalloc()Kees Cook
The vzalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vzalloc(a * b) with: vzalloc(array_size(a, b)) as well as handling cases of: vzalloc(a * b * c) with: vzalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vzalloc(4 * 1024) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( vzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | vzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( vzalloc( - sizeof(u8) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(__u8) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(char) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | vzalloc( - sizeof(u8) * COUNT + COUNT , ...) | vzalloc( - sizeof(__u8) * COUNT + COUNT , ...) | vzalloc( - sizeof(char) * COUNT + COUNT , ...) | vzalloc( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( vzalloc( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ vzalloc( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( vzalloc( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( vzalloc( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | vzalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( vzalloc( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( vzalloc(C1 * C2 * C3, ...) | vzalloc( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( vzalloc(C1 * C2, ...) | vzalloc( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>

The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This time we have a good set of changes to the core framework that do some general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for Actions Semi so it takes up some lines to add all the different types, and the Qualcomm diff is there because we add support for two SoCs and it's quite a bit of data. Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And then the long tail of driver updates for various fixes and stuff follows after that. Core: - debugfs cleanups removing error checking and an unused provider API - Removal of a clk init typedef that isn't used - Usage of match_string() to simplify parent string name matching - OF clk helpers moved to their own file (linux/of_clk.h) - Make clk warnings more readable across kernel versions New Drivers: - Qualcomm SDM845 GCC and Video clk controllers - Qualcomm MSM8998 GCC - Actions Semi S900 SoC support - Nuvoton npcm750 microcontroller clks - Amlogic axg AO clock controller Removed Drivers: - Deprecated Rockchip clk-gate driver Updates: - debugfs functions stopped checking return values - Support for the MSIOF module clocks on Rensas R-Car M3-N - Support for the new Rensas RZ/G1C and R-Car E3 SoCs - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs - Berlin and Amlogic SPDX tagging - Usage of of_clk_get_parent_count() in more places - Proper implementation of the CDEV1/2 clocks on Tegra20 - Allwinner H6 PRCM clock support and R40 EMAC support - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet - Round closest support for meson's mpll driver - Support for meson8b nand clocks and gxbb video decoder clocks - Mediatek mali clks - STM32MP1 fixes - Uniphier LD11/LD20 stream demux system clock" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) clk: qcom: Export clk_fabia_pll_configure() clk: bcm: Update and add Stingray clock entries dt-bindings: clk: Update Stingray binding doc clk-si544: Properly round requested frequency to nearest match clk: ingenic: jz4770: Add 150us delay after enabling VPU clock clk: ingenic: jz4770: Enable power of AHB1 bus after ungating VPU clock clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle clk: ingenic: jz4770: Change OTG from custom to standard gated clock clk: ingenic: Support specifying "wait for clock stable" delay clk: ingenic: Add support for clocks whose gate bit is inverted clk: use match_string() helper clk: bcm2835: use match_string() helper clk: Return void from debug_init op clk: remove clk_debugfs_add_file() clk: tegra: no need to check return value of debugfs_create functions clk: davinci: no need to check return value of debugfs_create functions clk: bcm2835: no need to check return value of debugfs_create functions clk: no need to check return value of debugfs_create functions clk: imx6: add EPIT clock support clk: mvebu: use correct bit for 98DX3236 NAND ...
2018-06-08soc: renesas: rcar-sysc: Make PM domain initialization more robustGeert Uytterhoeven
The quirk for R-Car E3 ES1.0 added in commit 086b399965a7ee7e ("soc: renesas: r8a77990-sysc: Add workaround for 3DG-{A,B}") makes the 3DG-A PM domain a subdomain of the 3DG-B PM domain. However, registering 3DG-A with its parent fails silently, as the 3DG-B PM domain hasn't been registered yet, and such failures are never reported. Fix this by: 1. Splitting PM Domain initialization in two steps, so all PM domains are registered before any child-parent links are established, 2. Reporting any failures in establishing child-parent relations. Check for and report pm_genpd_init() failures, too, as that function gained a return value in commit 7eb231c337e00735 ("PM / Domains: Convert pm_genpd_init() to return an error code").
