Merge tag 'omap-for-v5.2/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omap variants for dra7 mmc voltage and boot issues This series contains dra7 mmc voltage fixes, and fixes to the recent changes to probe devices with device tree data insteas of legacy platform data: - Two fixes for dra7 mmc that needs 1.8V mode disabled as in case of a reset, the bootrom will try to access the mmc card at 3.3V potentially damaging the card - Two regression fixes for am335x d_can. We must allow devices with no control registers for ti-sysc interconnect target module driver for at least d_can, and we remove the incorrect control registers for d_can. And we must configure the osc clock for d_can as otherwise register access may fail depending on the bootloader version - Four regression fixes for dra7 variant dts files to tag rtc and usb4 as disabled for dra71x and dra76x. These SoC variants do not have these devices, and got accidentally enabled when the L4 interconnect got defined in the dra7-l4.dtsi for the dra7 SoC family * tag 'omap-for-v5.2/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: dra71x: Disable usb4_tm target module ARM: dts: dra71x: Disable rtc target module ARM: dts: dra76x: Disable usb4_tm target module ARM: dts: dra76x: Disable rtc target module ARM: dts: dra76x: Update MMC2_HS200_MANUAL1 iodelay values ARM: dts: am57xx-idk: Remove support for voltage switching for SD card bus: ti-sysc: Handle devices with no control registers ARM: dts: Configure osc clock for d_can on am335x Signed-off-by: Olof Johansson <olof@lixom.net>
