2018-09-13soc: qcom: smem: a few last cleanupsAlex Elder
This patch contains several small cleanups: - In qcom_smem_enumerate_partitions(), change the "local_host" argument to have 16 bit unsigned type - Also in qcom_smem_enumerate_partitions(), change the type of the "host0" and "host1" local variables to be u16 - Fix error messages reporting host ids to use the right format specifier - Shorten the error messages as well, to fit on one line - Add a compile-time check to ensure the local host value passed to qcom_smem_enumerate_partitions() is in range Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>

2018-09-13soc: qcom: smem: introduce qcom_smem_partition_header()Alex Elder
Create a new function qcom_smem_partition_header() to encapsulate validating locating a partition header and validating information found within it. This will be built up over a few commits to make it more obvious how the common function is replacing duplicated code elsewhere. Initially it just verifies the header has the right magic number.

2018-09-13soc: qcom: smem: require order of host ids to matchAlex Elder
In qcom_smem_enumerate_partitions(), we find all partitions that have a given local host id in either its host0 or its host1 field in the partition table entry. We then verify that the header structure at the start of each partition also contains the same two host ids as is found in the table of contents. There is no requirement that the order of the two host ids be the same in the table of contents and in the partition header. This patch changes that, requiring host0 to in the partition table entry to equal host0 in the partition header structure (and similar for the host1 values).

2018-09-13soc: qcom: smem: verify both host ids in partition headerAlex Elder
The global partition is indicated by having both host values in its table of contents entry equal SMEM_GLOBAL_HOST=0xfffe. In qcom_smem_set_global_partition(), we check whether the header structure at the beginning of the partition contains that host value, but the check only verifies *one* of them. Change the check so the partition header must have SMEM_GLOBAL_HOST for *both* its host fields. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>

2018-09-13soc: qcom: smem: always ignore partitions with 0 offset or sizeAlex Elder
In qcom_smem_enumerate_partitions(), any partition table entry having a zero offset or size field is ignored. Move those checks earlier in the loop, because there's no sense in examining the host fields for those entries. Add the same checks in qcom_smem_set_global_partition(), so the scan for the global partition skips over these invalid entries. This allows a later check for zero size or offset once the global entry is found to be eliminated. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>

2018-09-13soc: qcom: geni: geni_se_clk_freq_match() should always accept multiplesDouglas Anderson
The geni_se_clk_freq_match() has some strange semantics. Specifically it is defined with two modes: 1. It can find a clock that's an exact multiple of the requested rate 2. It can find a non-exact match but it can't handle multiples then ...but callers should always be able to handle a clock that is a multiple of the requested clock so mode #2 doesn't really make sense. Let's change the semantics so that the non-exact match can also accept multiples and then change the code to handle that. The only caller of this code is the unlanded SPI driver [1] which currently passes "exact = True", thus it should be safe to change the semantics in this way. ...and, in fact, the SPI driver should likely be modified to pass "exact = False" (with the new semantics) since that will allow it to work with SPI devices that request a clock rate that doesn't exactly match a rate we can make.

2018-09-13soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()Douglas Anderson
The function clk_round_rate() is defined to return a "long", not an "unsigned long". That's because it might return a negative error code. Change the call in geni_se_clk_tbl_get() to check for errors. While we're at it, get rid of a useless init of "freq". NOTE: overall the idea that we should iterate over clk_round_rate() to try to reconstruct a table already present in the clock driver is questionable. Specifically: - This method relies on "clk_round_rate()" rounding up. - This method only works if the table is sorted and has no duplicates. ...this patch doesn't try to fix those problems, it just makes the error handling more correct.

New boards and systems: - Several Atmel at91-based boards from Laird - Marvell Armada388-based Helios4 board from SolidRun - Samsung Aires-based phones (s5pv210) - Allwinner A64-based Pinebook laptop In addition to the above, there's the usual amount of new devices described on existing platforms, fixes and tweaks and new minor variants of boards/platforms" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (478 commits) arm64: dts: sdm845: Add tsens nodes arm64: dts: msm8996: thermal: Initialise via DT and add second controller arm64: dts: sprd: Add one suspend timer arm64: dts: sprd: Add SC27XX ADC device arm64: dts: sprd: Add SC27XX eFuse device arm64: dts: sprd: Add SC27XX vibrator device arm64: dts: sprd: Add SC27XX breathing light controller device arm64: dts: meson-axg: add spdif-dit codec arm64: dts: meson-axg: add lineout codec arm64: dts: meson-axg: add linein codec arm64: dts: meson-axg: add tdm interfaces arm64: dts: meson-axg: add tdmout formatters arm64: dts: meson-axg: add tdmin formatters arm64: dts: meson-axg: add spdifout arm64: dts: rockchip: add led support for Firefly-RK3399 arm64: dts: rockchip: remove deprecated Type-C PHY properties on rk3399 arm64: dts: rockchip: add power button support for Firefly-RK3399 ARM: dts: aspeed: Add coprocessor interrupt controller arm64: dts: meson-axg: add audio arb reset controller arm64: dts: meson-axg: add usb power regulator ...
