Subject: [PATCH v2 00/11] Move PMC clocks into Tegra PMC driver
Date: Tue, 26 Nov 2019 20:59:22 -0800
Message-ID: <1574830773-14892-1-git-send-email-skomatineni@nvidia.com> (raw)

Tegra PMC has clk_out_1, clk_out_2, clk_out_3 and blink controls which
are currently registered by Tegra clock driver using clk_regiser_mux and
clk_register_gate which performs direct Tegra PMC register access.

When Tegra PMC is in secure mode, any access from non-secure world will
not go through.

This patch series adds these Tegra PMC clocks and blink controls to Tegra
PMC driver with PMC as clock provider and removed them from Tegra clock
driver. This also adds PMC specific clock id's to use in device tree and
removed clock ids of PMC clock from Tegra clock driver.

This series also includes patch to update clock provider from tegra_car
to pmc in the device tree tegra210-smaug.dts that uses clk_out_2 from PMC.

[v2]:	Changes between v1 and v2 are
	- v2 includes patches for adding clk_out_1, clk_out_2, clk_out_3,
	  blink controls to Tegra PMC driver and removing clk-tegra-pmc.
	- feedback related to pmc clocks in Tegra PMC driver from v1
	- Removed patches for WB0 PLLM overrides and PLLE IDDQ PMC programming
	  by the clock driver using helper functions from Tegra PMC.

 	  Note:
	  To use helper functions from PMC driver, PMC early init need to
	  happen prior to using helper functions and these helper functions are
	  for PLLM Override and PLLE IDDQ programming in PMC during PLLM/PLLE
	  clock registration which happen in clock_init prior to Tegra PMC
	  probe.
	  Moving PLLM/PLLE clocks registration to happen after Tegra PMC
	  impacts other clocks EMC, MC and corresponding tegra_emc_init and
	  tegra_mc_init.
	  This implementation of configuring PMC registers thru helper
	  functions in clock driver needs proper changes across PMC, Clock,
	  EMC and MC inits to have it work across all Tegra platforms.

	  Currently PLLM Override is not enabled in the bootloader so proper
	  patches for this fix will be taken care separately.

[v1]:	v1 includes patches for below fixes.
	- adding clk_out_1, clk_out_2, clk_out_3, blink controls to Tegra PMC
	  driver and removing clk-tegra-pmc.
	- updated clock provider from tegra_car to pmc in the device tree
	  tegra210-smaug.dts that uses clk_out_2.
	- Added helper functions in PMC driver for WB0 PLLM overrides and PLLE
	  IDDQ programming to use by clock driver and updated clock driver to
	  use these helper functions and removed direct PMC access from clock
	  driver and all pmc base address references in clock driver.
