Driver changes for omaps for genpd for v5.11 merge window This series of changes allows booting am335x with genpd and device tree data without the legacy platform data. Also at least am437x can be booted with gendp with power domain and dts data. The SoC specific dts changes will be a separate pull request. We need the following driver changes merged before the dts changes can be done: - platform code needs a few improvments to probe l4_wkup first for clocks, and to bail out when there is no platform data - ti-sysc driver needs a non-urgent fix for asserting rstctrl reset only after disabling the clocks, to probe modules with no known control registers, and added quirk handling for gpmc devices - omap-prm driver needs a non-urgent fix for reset status bit, support added for pm_clk, and then we add the rest of am335x power domain data - clock driver for am335x needs to keep l3_main clock enabled with genpd for suspend and resume to work - wkup_m3 remoteproc driver needs support added for reset control if available instead of the legacy pdata callbacks - pm33xx driver needs PM runtime support added for genpd The am335x specific driver changes for the clock, wkup_m3, pm33xx and remoteproc drivers are quite trivial and have not caused merge conflicts in Linux next. I did not get acks for these changes except from Santosh but had already pushed out the branch already at that point. So I've added the related driver maintainers to Cc. * tag 'omap-for-v5.11/genpd-drivers-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: remoteproc/wkup_m3: Use reset control driver if available soc: ti: pm33xx: Enable basic PM runtime support for genpd soc: ti: omap-prm: am3: add genpd support for remaining PRM instances soc: ti: omap-prm: Add pm_clk for genpd clk: ti: am33xx: Keep am3 l3 main clock always on for genpd bus: ti-sysc: Implement GPMC debug quirk to drop platform data bus: ti-sysc: Support modules without control registers ARM: OMAP2+: Probe PRCM first to probe l4_wkup with simple-pm-bus ARM: OMAP2+: Check for inited flag bus: ti-sysc: Assert reset only after disabling clocks soc: ti: omap-prm: Do not check rstst bit on deassert if already deasserted bus: ti-sysc: Fix bogus resetdone warning on enable for cpsw bus: ti-sysc: Fix reset status check for modules with quirks ARM: OMAP2+: Fix missing select PM_GENERIC_DOMAINS_OF ARM: OMAP2+: Fix location for select PM_GENERIC_DOMAINS Link: https://lore.kernel.org/r/pull-1606806458-694517@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de> |
