git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into devel pinctrl: sh-pfc: Updates for v5.5 - Split R-Car H3 support in two independent drivers, - Miscellaneous fixes and cleanups.
2020-01-08pinctrl: sh-pfc: Split R-Car H3 support in two independent driversGeert Uytterhoeven
Despite using the same compatible values ("r8a7795"-based) because of historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+ (R8A77951) are really different SoCs, with different part numbers, and with different Pin Function Controller blocks. Reflect this in the pinctrl configuration, by replacing the existing CONFIG_PINCTRL_PFC_R8A7795 symbol by two new config symbols: CONFIG_PINCTRL_PFC_R8A77950 and CONFIG_PINCTRL_PFC_R8A77951. The latter are selected automatically, depending on the soon-to-be-introduced corresponding SoC-specific config options, and on the current common config option, to relax dependencies. Rename the individual pin control driver source files from pfc-r8a7795-es1.c to pfc-r8a77950.c, and from pfc-r8a7795.c to pfc-r8a77951.c, and make them truly independent. As both SoCs share the same compatible value, special care must be taken to match them to the correct pin control driver, if support for it is included in the running kernel. This will allow making support for early R-Car H3 revisions optional, the largest share of which is taken by the pin control driver.

2020-01-07pinctrl: meson: meson8b: add the GPIOH pinmux settings for ETH_RXD{2,3}Martin Blumenstingl
GPIOH_5 and GPIOH_6 can have two Ethernet related functions: - GPIOH_5 can be ETH_TXD1 or ETH_RXD3 - GPIOH_6 can be ETH_TXD0 or ETH_RXD2 Add the bits for eth_rxd3_h and eth_rxd2_h so the ETH_RXD function can be disabled when using the ETH_TXD function of GPIOH_{5,6}. No problem was observed so far, but in theory this could lead to two different signals being routed to the same pad (which could break Ethernet).

2019-12-31pinctrl: sh-pfc: sh7269: Fix CAN function GPIOsGeert Uytterhoeven
pinmux_func_gpios[] contains a hole due to the missing function GPIO definition for the "CTX0&CTX1" signal, which is the logical "AND" of the first two CAN outputs. A closer look reveals other issues: - Some functionality is available on alternative pins, but the PINMUX_DATA() entries is using the wrong marks, - Several configurations are missing. Fix this by: - Renaming CTX0CTX1CTX2_MARK, CRX0CRX1_PJ22_MARK, and CRX0CRX1CRX2_PJ20_MARK to CTX0_CTX1_CTX2_MARK, CRX0_CRX1_PJ22_MARK, resp. CRX0_CRX1_CRX2_PJ20_MARK for consistency with the corresponding enum IDs, - Adding all missing enum IDs and marks, - Use the right (*_PJ2x) variants for alternative pins, - Adding all missing configurations to pinmux_data[], - Adding all missing function GPIO definitions to pinmux_func_gpios[].

2019-12-30pinctrl: Allow modules to use pinctrl_[un]register_mappingsHans de Goede
Currently only the drivers/pinctrl/devicetree.c code allows registering pinctrl-mappings which may later be unregistered, all other mappings are assumed to be permanent. Non-dt platforms may also want to register pinctrl mappings from code which is build as a module, which requires being able to unregister the mapping when the module is unloaded to avoid dangling pointers. To allow unregistering the mappings the devicetree code uses 2 internal functions: pinctrl_register_map and pinctrl_unregister_map. pinctrl_register_map allows the devicetree code to tell the core to not memdup the mappings as it retains ownership of them and pinctrl_unregister_map does the unregistering, note this only works when the mappings where not memdupped. The only code relying on the memdup/shallow-copy done by pinctrl_register_mappings is arch/arm/mach-u300/core.c this commit replaces the __initdata with const, so that the shallow-copy is no longer necessary. After that we can get rid of the internal pinctrl_unregister_map function and just use pinctrl_register_mappings directly everywhere. This commit also renames pinctrl_unregister_map to pinctrl_unregister_mappings so that its naming matches its pinctrl_register_mappings counter-part and exports it. Together these 2 changes will allow non-dt platform code to register pinctrl-mappings from modules without breaking things on module unload (as they can now unregister the mapping on unload).

2019-12-20net: ena: fix issues in setting interrupt moderation params in ethtoolArthur Kiyanovski
Issue 1: -------- Reproduction steps: 1. sudo ethtool -C eth0 rx-usecs 128 2. sudo ethtool -C eth0 adaptive-rx on 3. sudo ethtool -C eth0 adaptive-rx off 4. ethtool -c eth0 expected output: rx-usecs 128 actual output: rx-usecs 0 Reason for issue: In stage 3, ethtool userspace calls first the ena_get_coalesce() handler to get the current value of all properties, and then the ena_set_coalesce() handler. When ena_get_coalesce() is called the adaptive interrupt moderation is still on. There is an if in the code that returns the rx_coalesce_usecs only if the adaptive interrupt moderation is off. And since it is still on, rx_coalesce_usecs is not set, meaning it stays 0. Solution to issue: Remove this if static interrupt moderation intervals have nothing to do with dynamic ones. Issue 2: -------- Reproduction steps: 1. sudo ethtool -C eth0 adaptive-rx on 2. sudo ethtool -C eth0 rx-usecs 128 3. ethtool -c eth0 expected output: rx-usecs 128 actual output: rx-usecs 0 Reason for issue: In stage 2, when ena_set_coalesce() is called, the handler tests if rx adaptive interrupt moderation is on, and if it is, it returns before getting to the part in the function that sets the rx non-adaptive interrupt moderation interval. Solution to issue: Remove the return from the function when rx adaptive interrupt moderation is on. Also cleaned up the fixed code in ena_set_coalesce by grouping together adaptive interrupt moderation toggling, and using && instead of nested ifs.

2019-12-20net: ena: fix default tx interrupt moderation intervalArthur Kiyanovski
Current default non-adaptive tx interrupt moderation interval is 196 us. This value is too high and might cause the tx queue to fill up. In this commit we set the default non-adaptive tx interrupt moderation interval to 64 us in order to: 1. Reduce the probability of the queue filling-up (when compared to the current default value of 196 us). 2. Reduce unnecessary tx interrupt overhead (which happens if we set the default tx interval to 0). We determined experimentally that 64 us is an optimal value that reduces interrupt rate by more than 20% without affecting performance.

2019-12-20s390/qeth: fix promiscuous mode after resetJulian Wiedmann
When managing the promiscuous mode during an RX modeset, qeth caches the current HW state to avoid repeated programming of the same state on each modeset. But while tearing down a device, we forget to clear the cached state. So when the device is later set online again, the initial RX modeset doesn't program the promiscuous mode since we believe it is already enabled. Fix this by clearing the cached state in the tear-down path. Note that for the SBP variant of promiscuous mode, this accidentally works right now because we unconditionally restore the SBP role while re-initializing.

This has one exynos fix, and a bunch of i915 core and i915 GVT fixes. Summary: exynos: - component delete fix i915: - Fix to drop an unused and harmful display W/A - Fix to define EHL power wells independent of ICL - Fix for priority inversion on bonded requests - Fix in mmio offset calculation of DSB instance - Fix memory leak from get_task_pid when banning clients - Fixes to avoid dereference of uninitialized ops in dma_fence tracing and keep reference to execbuf object until submitted. - vGPU state setting locking fix (Zhenyu) - Fix vGPU display dmabuf as read-only (Zhenyu) - Properly handle vGPU display dmabuf page pin when rendering (Tina) - Fix one guest boot warning to handle guc reset state (Fred)" * tag 'drm-fixes-2019-12-21' of git://anongit.freedesktop.org/drm/drm: drm/exynos: gsc: add missed component_del drm/i915: Fix pid leak with banned clients drm/i915/gem: Keep request alive while attaching fences drm/i915: Fix WARN_ON condition for cursor plane ddb allocation drm/i915/gvt: Fix guest boot warning drm/i915/tgl: Drop Wa#1178 drm/i915/ehl: Define EHL powerwells independently of ICL drm/i915: Set fence_work.ops before dma_fence_init drm/i915: Copy across scheduler behaviour flags across submit fences drm/i915/dsb: Fix in mmio offset calculation of DSB instance drm/i915/gvt: Pin vgpu dma address before using drm/i915/gvt: set guest display buffer as readonly drm/i915/gvt: use vgpu lock for active state setting
