memory: tegra: Clean up error messages

2019-01-16T12:54:13Z

Make all messages to start with a lower case and don't unnecessarily go over 80 chars in the code. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Do not ask for IRQ sharing

2019-01-16T12:54:13Z

Memory Controller driver never shared IRQ with any other driver and very unlikely that it will. Hence there is no need to request IRQ sharing and the corresponding flag can be dropped safely. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Do not try to probe SMMU on Tegra20

2019-01-16T12:54:13Z

Tegra20 doesn't have SMMU. Move out checking of the SMMU presence from the SMMU driver into the Memory Controller driver. This change makes code consistent in regards to how GART/SMMU presence checking is performed. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

iommu/tegra: gart: Integrate with Memory Controller driver

2019-01-16T12:54:12Z

The device-tree binding has been changed. There is no separate GART device anymore, it is squashed into the Memory Controller. Integrate GART module with the MC in a way it is done for the SMMU on Tegra30+. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Use relaxed versions of readl/writel

2019-01-16T12:54:12Z

There is no need for inserting of memory barriers to access registers of Memory Controller. Hence use the relaxed versions of the accessors. Signed-off-by: Dmitry Osipenko Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

memory: tegra: Use of_device_get_match_data()

2019-01-16T12:54:12Z

There is no need to match device with the DT node since it was already matched, use of_device_get_match_data() helper to get the match-data. Signed-off-by: Dmitry Osipenko Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

memory: tegra: Read client ID on GART page fault

2019-01-16T12:54:11Z

With the device tree binding changes, now Memory Controller has access to GART registers. Hence it is now possible to read client ID on GART page fault to get information about what memory client causes the fault. Signed-off-by: Dmitry Osipenko Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

memory: tegra: Adapt to Tegra20 device-tree binding changes

2019-01-16T12:54:11Z

The tegra20-mc device-tree binding has been changed, GART has been squashed into Memory Controller and now the clock property is mandatory for Tegra20, the DT compatible has been changed as well. Adapt driver to the DT changes. Signed-off-by: Dmitry Osipenko Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

memory: tegra: Don't invoke Tegra30+ specific memory timing setup on Tegra20

2019-01-16T12:54:11Z

This fixes irrelevant "tegra-mc 7000f000.memory-controller: no memory timings for RAM code 0 registered" warning message during of kernels boot-up on Tegra20. Fixes: a8d502fd3348 ("memory: tegra: Squash tegra20-mc into common tegra-mc driver") Signed-off-by: Dmitry Osipenko Acked-by: Jon Hunter Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2019-01-05T19:30:37Z

Pull more ARM SoC updates from Olof Johansson: "A few updates that we merged late but are low risk for regressions for other platforms (and a few other straggling patches): - I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in here. They're for a driver for the PL353 SRAM controller and a build fix for the qualcomm scm driver. - A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated Vivante GPU, 256MB RAM, Wifi). This includes some acked platform-specific drivers (serial, etc). This also include DTs for two boards with this SoC, OrangePi 2G and OrangePi i86. - i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K video playback offload). This is the first i.MX 64-bit SoC. - Some minor updates to Samsung boards (adding a few peripherals in DTs). - Small rework for SMP bootup on STi platforms. - A couple of TEE driver fixes. - A couple of new config options (bcm2835 thermal, Uniphier MDMAC) enabled in defconfigs" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (27 commits) ARM: multi_v7_defconfig: enable CONFIG_UNIPHIER_MDMAC arm64: defconfig: Re-enable bcm2835-thermal driver MAINTAINERS: Add entry for RDA Micro SoC architecture tty: serial: Add RDA8810PL UART driver ARM: dts: rda8810pl: Add interrupt support for UART dt-bindings: serial: Document RDA Micro UART ARM: dts: rda8810pl: Add timer support ARM: dts: Add devicetree for OrangePi i96 board ARM: dts: Add devicetree for OrangePi 2G IoT board ARM: dts: Add devicetree for RDA8810PL SoC ARM: Prepare RDA8810PL SoC dt-bindings: arm: Document RDA8810PL and reference boards dt-bindings: Add RDA Micro vendor prefix ARM: sti: remove pen_release and boot_lock arm64: dts: exynos: Add Bluetooth chip to TM2(e) boards arm64: dts: imx8mq-evk: enable watchdog arm64: dts: imx8mq: add watchdog devices MAINTAINERS: add i.MX8 DT path to i.MX architecture arm64: add support for i.MX8M EVK board arm64: add basic DTS for i.MX8MQ ...
