lpcg's arg0 should use clock indices instead of index.
pwm0_lpcg: clock-controller@5d400000 {
... // Col1 Col2
clocks = <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 0 0
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 1 1
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 2 4
<&lsio_bus_clk>, // 3 5
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>; // 4 6
clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_1>,
<IMX_LPCG_CLK_4>, <IMX_LPCG_CLK_5>,
<IMX_LPCG_CLK_6>;
};
Col1: index, which exited dts try to get.
Col2: actual index in lpcg driver.
pwm1 {
....
clocks = <&pwm1_lpcg 4>, <&pwm1_lpcg 1>;
^^ ^^
should be:
clocks = <&pwm1_lpcg IMX_LPCG_CLK_6>, <&pwm1_lpcg IMX_LPCG_CLK_1>;
};
Arg0 is divided by 4 in lpcg driver, so index 0 and 1 will be get by pwm
driver, which are same as IMX_LPCG_CLK_6 and IMX_LPCG_CLK_1. Even it can
work, but code logic is wrong. Fixed it by use correct indices.

You should not describe DT in terms of Linux driver.

This base on downstream dts code. Downstream code use index in 'Col1' to
get clock.
For example:
<&pwm0_lpcg 3> means &lsio_bus_clk.
When someone do upstream, miss understand or omit upsteam lpcg driver's
difference between downstream and upstream version. And it also work even
index is wrong.
I realize this problem when I try to enable audio device for qm. The
difference cause audio can't work. The grep lpcg [0-9] to find this
problem.

It just descript the actual hehavior in current drivers to explain why it
can work even arg0 is wrong.
for example: <&pwm0_lpcg 4>, developer intent to get
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>; // 4 6
but lpcg driver device device arg0 (4) by 4, get 1. So below clock return
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 1 1
Both it is IMX_SC_PM_CLK_PER, so pwm works luckly.
But correct code should be <&pwm0_lpcg IMX_LPCG_CLK_6>.

Arg0 is divided by 4 in lpcg driver. So lpcg will do dummy enable. Fix it
by use correct clock indices.

Arg0 is divided by 4 in lpcg driver. <&spi0_lpcg 0> and <&spi0_lpcg 1> are
IMX_SC_PM_CLK_PER. Although code can work, code logic is wrong. It should
use IMX_LPCG_CLK_0 and IMX_LPCG_CLK_4 for lpcg arg0.

Arg0 will be divided by 4 in lcpg driver, so pwm will get IMX_SC_PM_CLK_PER
by <&adma_pwm_lpcg 1>, <&adma_pwm_lpcg 0>. Although function can work, code
logic is wrong. Fix it by use correct indices.
