gpu: host1x: syncpt: Request syncpoints per client

2017-10-20T12:19:51Z

Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. Signed-off-by: Thierry Reding

gpu: host1x: Refactor channel allocation code

2017-06-15T12:25:38Z

This is largely a rewrite of the Host1x channel allocation code, bringing several changes: - The previous code could deadlock due to an interaction between the 'reflock' mutex and CDMA timeout handling. This gets rid of the mutex. - Support for more than 32 channels, required for Tegra186 - General refactoring, including better encapsulation of channel ownership handling into channel.c Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Fix error handling

It is likely that checking 'gr3d->clk_secondary' instead of 'gr3d->clk' is expected here. Signed-off-by: Christophe JAILLET Reviewed-by: Alexandre Courbot Signed-off-by: Thierry Reding

Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-08-08T18:00:26Z

Pull ARM SoC cleanups from Olof Johansson: "This merge window brings a good size of cleanups on various platforms. Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...

drm/tegra: add MODULE_DEVICE_TABLEs

2014-08-04T08:07:39Z

When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow the module to be auto-loaded since the module will match the devices instantiated from device tree. (Notes for stable: in 3.14+, just git rm any conflicting file, since they are added in later kernels. For 3.13 and below, manual merging will be needed) Cc: Signed-off-by: Stephen Warren Signed-off-by: Thierry Reding

ARM: tegra: Convert PMC to a driver

drm/tegra: Remove host1x drm_bus implementation

Tegra's clock driver now provides an implementation of the common reset API (include/linux/reset.h). Use this instead of the old Tegra- specific API; that will soon be removed.
