This is driver enables support for the low power domain SRTC features: - 32-bit MSB of non-rollover time counter - 32-bit alarm register Based on: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01 v2: - have seperate patches for dt-binding, CONFIG option, imx53.dtsi and driver - add SPDX-License-Identifier and cleanup copyright notice - replace __raw_readl/writel() with readl/writel() - fix PM_SLEEP callbacks - add CONFIG_RTC_DRV_MXC_V2 to build rtc-mxc_v2.c - remove misleading or obvious comments and fix style of the remaining - avoid endless loop while waiting for hw - implement consistent locking; make spinlock a member of dev struct - enable clk only for register accesses - remove all udelay() calls since they are obsolete or redundant (we are already waiting for register flags to change) - init platform_data before registering irq callback - let set_time() fail, when 32 bit rtc counter exceeded - make names more consistent - cleanup and reorder includes - cleanup and remove unused defines To: Alessandro Zummo To: Alexandre Belloni Cc: Rob Herring Cc: Mark Rutland (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) Cc: linux-rtc@vger.kernel.org (open list:REAL TIME CLOCK (RTC) SUBSYSTEM) Cc: devicetree@vger.kernel.org (open list:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) Cc: linux-kernel@vger.kernel.org (open list) Cc: Fabio Estevam Cc: Juergen Borleis Cc: Noel Vellemans Cc: Shawn Guo Cc: Sascha Hauer (maintainer:ARM/FREESCALE IMX / MXC ARM ARCHITECTURE) Cc: Russell King (maintainer:ARM PORT) Cc: linux-arm-kernel@lists.infradead.org (moderated list:ARM/FREESCALE IMX / MXC ARM ARCHITECTURE) Cc: Philippe Ombredanne Cc: Lothar Waßmann Patrick Bruenn (5): dt-bindings: rtc: add bindings for i.MX53 SRTC ARM: dts: imx53: add srtc node rtc: mxc_v2: add driver for i.MX53 SRTC ARM: imx_v4_v5_defconfig: enable RTC_DRV_MXC_V2 rtc: add mxc driver for i.MX53 SRTC .../devicetree/bindings/rtc/rtc-mxc_v2.txt | 17 + arch/arm/boot/dts/imx53.dtsi | 4 +- arch/arm/configs/imx_v4_v5_defconfig | 1 + drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-mxc_v2.c | 433 +++++++++++++++++++++ 6 files changed, 463 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/rtc/rtc-mxc_v2.txt create mode 100644 drivers/rtc/rtc-mxc_v2.c -- 2.11.0
