Merge tag 'omap-for-v5.3/ti-sysc-dt-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/dt
ti-sysc dts changes for v5.3 We can now drop the custom dts property "ti,hwmods" for drivers that have the ti-sysc interconnect target module configured in dts. Let's start with a minimal changes to omap4 uart and mmc. We use omap4 as the starting point as it has runtime PM implemented and all the omap variants after that are based on it with similar clkctrl clock for the modules. More devices will be updated later on as they get tested. Note that these changes are based on the related ti-sysc driver changes. * tag 'omap-for-v5.3/ti-sysc-dt-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (21 commits) ARM: dts: Drop legacy custom hwmods property for omap4 mmc ARM: dts: Drop legacy custom hwmods property for omap4 uart bus: ti-sysc: Detect uarts also on omap34xx bus: ti-sysc: Do rstctrl reset handling in two phases bus: ti-sysc: Add support for disabling module without legacy mode bus: ti-sysc: Set ENAWAKEUP if available bus: ti-sysc: Handle swsup idle mode quirks bus: ti-sysc: Handle clockactivity for enable and disable bus: ti-sysc: Enable interconnect target module autoidle bit on enable bus: ti-sysc: Allow QUIRK_LEGACY_IDLE even if legacy_mode is not set bus: ti-sysc: Make OCP reset work for sysstatus and sysconfig reset bits bus: ti-sysc: Support 16-bit writes too bus: ti-sysc: Add support for missing clockdomain handling 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 ...
