Subject: [PATCH V3 0/8] clk: imx93: new gate API and composite update

From: Peng Fan <peng.fan@....com>


V3:
 Add R-b
 Drop of_match_ptr in patch 2, so I drop Abel's R-b in this patch.

V2:
 Add A-b from Rob
 Add a new patch 2 reported by intel test robot
 Use Abel's new address for sending mail

The current clk driver use gate API as i.MX8M*, the gate2 API use 0x3 as
val/mask, however i.MX93 LPCG DIRECT use BIT0 as on/off gate. So clk
disable unused actually not gate off the LPCG clocks.
And i.MX93 has AUTHEN feature, so add a new API to support i.MX93 clk gate.

i.MX93 CCM ROOT has slice busy check bit when updating register value, add
check. CCM ROOT also has AUTHEN whitelist, so add DID check.

Besides the gate/composite update, add MU[X] and SAI IPG clk in this
patchset

This patchset has got reviewed in NXP internal, so I keep R-b tag here.
For those that have some change compared with downstream, R-b tag dropped.

Peng Fan (8):
  dt-bindings: clock: imx93-clock: add more MU/SAI clocks
  clk: imx93: drop of_match_ptr
  clk: imx: clk-composite-93: check slice busy
  clk: imx: clk-composite-93: check white_list
  clk: imx: add i.MX93 clk gate
  clk: imx93: switch to use new clk gate API
  clk: imx93: add MU1/2 clock
  clk: imx93: add SAI IPG clk
