[RESEND PATCH 0/4] clk: mediatek: modularize COMMON_CLK_MT6779

[RESEND PATCH 0/4] clk: mediatek: modularize COMMON_CLK_MT6779

[Miles Chen]

This patch set makes COMMON_CLK_MEDIATEK and COMMON_CLK_MT6779*
be able to built as kernel modules. Necessary symbols are exported
in this patch.

In previous discussion [1], Stephen commented that there must
be a user before exporting a symbol:

"
Is the mediatek driver compilable as a module? Last time I checked it
wasn't a module. I want an upstream modular driver that uses the symbol.
Otherwise we're exporting symbols when it doesn't need to be.
"

How does this work? builtin_platform_driver() means that it's not
modular code. Shouldn't that be module_platform_driver()? Have you tried
loading and unloading the module?

sorry for my late response. 

Thanks for pointing this out. I have the same question when I was
building this patch. That time I found some examples where
they are using builtin_platform_driver and can be built as 
kernel modules:

config CLK_IMX8QXP (tristate) && drivers/clk/imx/clk-imx8qxp-lpcg.c
config CLK_RK3399 (tristate) && drivers/clk/rockchip/clk-rk3399.c

my load test:
load these moduless and do 'lsmod' on v5.14-rc1/mt6779 environment:

clk_mt6779_aud 16384 0 [permanent], Live 0xffff800008fd8000
clk_mt6779_mfg 16384 0 [permanent], Live 0xffff800008fd0000
clk_mt6779_venc 16384 0 [permanent], Live 0xffff800008fc8000
clk_mt6779_vdec 16384 0 [permanent], Live 0xffff800008fc0000
clk_mt6779_cam 16384 0 [permanent], Live 0xffff800008fb8000
clk_mt6779_ipe 16384 0 [permanent], Live 0xffff800008fb0000
clk_mt6779_img 16384 0 [permanent], Live 0xffff800008fa8000
clk_mt6779_mm 16384 0 [permanent], Live 0xffff800008fa0000

I did not test 'unload' kernel modules because I did not
define module_exit in this patch.

But as you pointed out, it should be module_platform_driver().
I will use module_platform_driver() in the next patch.

sorry for my late response. 

Thanks for pointing this out. I have the same question when I was
building this patch. That time I found some examples where
they are using builtin_platform_driver and can be built as 
kernel modules:

config CLK_IMX8QXP (tristate) && drivers/clk/imx/clk-imx8qxp-lpcg.c
config CLK_RK3399 (tristate) && drivers/clk/rockchip/clk-rk3399.c

my load test:
load these moduless and do 'lsmod' on v5.14-rc1/mt6779 environment:

clk_mt6779_aud 16384 0 [permanent], Live 0xffff800008fd8000
clk_mt6779_mfg 16384 0 [permanent], Live 0xffff800008fd0000
clk_mt6779_venc 16384 0 [permanent], Live 0xffff800008fc8000
clk_mt6779_vdec 16384 0 [permanent], Live 0xffff800008fc0000
clk_mt6779_cam 16384 0 [permanent], Live 0xffff800008fb8000
clk_mt6779_ipe 16384 0 [permanent], Live 0xffff800008fb0000
clk_mt6779_img 16384 0 [permanent], Live 0xffff800008fa8000
clk_mt6779_mm 16384 0 [permanent], Live 0xffff800008fa0000

I did not test 'unload' kernel modules because I did not
define module_exit in this patch.

But as you pointed out, it should be module_platform_driver().
I will use module_platform_driver() in the next patch.

We should fix those drivers. Care to send a patch?

No problem. I will check drviers/clk and submit fix patches.
