2020-05-06reset: imx7: Add support for i.MX8MP SoCAnson Huang
i.MX8MP is a new SoC of i.MX8M family, it has same src IP inside but with different module layout, add support for it. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2019-08-01dt-bindings: reset: Fix typo in imx8mq resetsGuido Günther
Some of the mipi dsi resets were called IMX8MQ_RESET_MIPI_DIS__ instead of IMX8MQ_RESET_MIPI_DSI__ Since they're DSI related this looks like a typo. This fixes the only in tree user as well to not break bisecting.

The audio driver went in this merge window, and these changes have been in -next for a while (just not in our tree). - Power management fixes for IOMMU on Rockchip platforms, getting closer to kexec working on them, including Chromebooks. - Another pass updating "arm,psci" -> "psci" for some properties that have snuck in since last time it was done" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: iommu/rockchip: Move irq request past pm_runtime_enable iommu/rockchip: Handle errors returned from PM framework arm64: rockchip: Force CONFIG_PM on Rockchip systems ARM: rockchip: Force CONFIG_PM on Rockchip systems arm64: dts: Fix various entry-method properties to reflect documentation reset: imx7: Fix always writing bits as 0 reset: meson: add meson audio arb driver reset: meson: add dt-bindings for meson-axg audio arb
2018-07-23reset: imx7: Fix always writing bits as 0Leonard Crestez
Right now the only user of reset-imx7 is pci-imx6 and the reset_control_assert and deassert calls on pciephy_reset don't toggle the PCIEPHY_BTN and PCIEPHY_G_RST bits as expected. Fix this by writing 1 or 0 respectively. The reference manual is not very clear regarding SRC_PCIEPHY_RCR but for other registers like MIPIPHY and HSICPHY the bits are explicitly documented as "1 means assert, 0 means deassert". The values are still reversed for IMX7_RESET_PCIE_CTRL_APPS_EN.

2018-07-07headers: separate linux/mod_devicetable.h from linux/platform_device.hRandy Dunlap
At over 4000 #includes, <linux/platform_device.h> is the 9th most #included header file in the Linux kernel. It does not need <linux/mod_devicetable.h>, so drop that header and explicitly add <linux/mod_devicetable.h> to source files that need it. 4146 #include <linux/platform_device.h> After this patch, there are 225 files that use <linux/mod_devicetable.h>, for a reduction of around 3900 times that <linux/mod_devicetable.h> does not have to be read & parsed. 225 #include <linux/mod_devicetable.h> This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.
