The following series are intended to prepare the mtk-mmsys driver to
allow different DDP (Data Display Path) function call per SoC.
base 5.11-rc1
change since v3:
- move register operation into mmsys path select function
Yongqiang Niu (10):
soc: mediatek: mmsys: create mmsys folder
soc: mediatek: mmsys: Create struct mtk_mmsys to store context data
soc: mediatek: mmsys: move register operation into mmsys path select
function
soc: mediatek: mmsys: Use function call for setting the routing
registers
soc: mediatek: mmsys: add mt8183 function call for setting the routing
registers
soc: mediatek: mmsys: add component OVL_2L2
soc: mediatek: mmsys: add component POSTMASK
soc: mediatek: mmsys: add component RDMA4
soc: mediatek: mmsys: Use function call for setting mmsys ovl mout
register
soc: mediatek: mmsys: add mt8192 mmsys support

the mmsys will more and more complicated after support
more and more SoCs, add an independent folder will be
more clear

the mmsys will more and more complicated after support
more and more SoCs, add an independent folder will be
more clear

the mmsys will more and more complicated after support
more and more SoCs, add an independent folder will be
more clear

the mmsys will more and more complicated after support
more and more SoCs, add an independent folder will be
more clear

mt2701 and mt8173 ovl mout en already different.
mt2701 ovl mout en register offset is 0x30
mt8173 olv mout en register offset is 0x40
only the use case is different;
mt2701 ovl->color0
mt8173 ovl->rmda0
there make different define for this different.
#define DISP_REG_CONFIG_DISP_OVL0_MOUT_EN 0x040
#define DISP_REG_CONFIG_DISP_OVL_MOUT_EN 0x030
for the future mt8183, ovl mout en register offset will change to
0xf00
this is only one different sample, there will be more and more
different, so we add this patch for different soc

this is only one different sample, there will be more and more
different, so we add this patch for different soc

mt2701 and mt8173 ovl mout en already different.
mt2701 ovl mout en register offset is 0x30
mt8173 olv mout en register offset is 0x40
only the use case is different;
mt2701 ovl->color0
mt8173 ovl->rmda0
there make different define for this different.
#define DISP_REG_CONFIG_DISP_OVL0_MOUT_EN 0x040
#define DISP_REG_CONFIG_DISP_OVL_MOUT_EN 0x030
for the future mt8183, ovl mout en register offset will change to
0xf00
this is only one different sample, there will be more and more
different, so we add this patch for different soc

mt2701 and mt8173 ovl mout en already different.
mt2701 ovl mout en register offset is 0x30
mt8173 olv mout en register offset is 0x40
only the use case is different;
mt2701 ovl->color0
mt8173 ovl->rmda0
there make different define for this different.
#define DISP_REG_CONFIG_DISP_OVL0_MOUT_EN 0x040
#define DISP_REG_CONFIG_DISP_OVL_MOUT_EN 0x030
for the future mt8183, ovl mout en register offset will change to
0xf00
this is only one different sample, there will be more and more
different, so we add this patch for different soc

That does not explain why you want to put the read and write calls in a per SoC
part, they are the same for all supported SoCs.
Anyway after having a second thought, I don't like this approach at all. I think
splitting up the code in several SoCs to not bloat the driver is a good thing,
but not as it is done in this series.
I'd prefer to use a lookup table as Enric did in his first approach [1]. We
could then add this table in a per SoC header file.

That does not explain why you want to put the read and write calls in a per SoC
part, they are the same for all supported SoCs.
Anyway after having a second thought, I don't like this approach at all. I think
splitting up the code in several SoCs to not bloat the driver is a good thing,
but not as it is done in this series.
I'd prefer to use a lookup table as Enric did in his first approach [1]. We
could then add this table in a per SoC header file.

Matthias

That does not explain why you want to put the read and write calls in a per SoC
part, they are the same for all supported SoCs.
Anyway after having a second thought, I don't like this approach at all. I think
splitting up the code in several SoCs to not bloat the driver is a good thing,
but not as it is done in this series.
I'd prefer to use a lookup table as Enric did in his first approach [1]. We
could then add this table in a per SoC header file.
Regards,
Matthias

Actually, setting the registers for routing, use multiple 'if-else' for different
routes, but this code would be more and more complicated while we
support more and more SoCs. Change that and use a function call per SoC so the
code will be more portable and clear.

Actually, setting the registers for routing, use multiple 'if-else' for different
routes, but this code would be more and more complicated while we
support more and more SoCs. Change that and use a function call per SoC so the
code will be more portable and clear.

Actually, setting the registers for routing, use multiple 'if-else' for different
routes, but this code would be more and more complicated while we
support more and more SoCs. Change that and use a function call per SoC so the
code will be more portable and clear.

Actually, setting the registers for routing, use multiple 'if-else' for different
routes, but this code would be more and more complicated while we
support more and more SoCs. Change that and use a function call per SoC so the
code will be more portable and clear.
