[MIYOO_KBD] Fix keyboard for RS-77

[tiopex]

On RS-77 (yet another SUP M3 clone) when IN_PA1 == 1 then IN_2 cannot go to 1. So it needs to add the condition that IN_PA1 must always be 0 when checking IN_2.

If you're refering TriForceX/MiyooCFW#518 then it should be MY_L1 (from the face buttons layout) which can't be registered with LEFT/RIGHT pressed from what he says (or is it opposite?). Does that button combo works on your device?

Well I can not test it on real HW, but while we are at it then we might as well do another kbd.variant for RS-77 and one more for M3S while commenting out below code:

kernel/drivers/input/keyboard/miyoo_kbd.c

Lines 430 to 432 in 70c8615

	if(gpio_get_value(IN_1) == 1 && gpio_get_value(IN_2) == 0){
	val|= MY_START;
	}

From what I heard they don't explicit this issue as SUP M3 do.

According iotester it is IN_PA1

Well is he using official build from our actions runner?

I think so, on other screen I see boot logo with miyoocfw

Hello, thank you very much for your reply. I am using this RS77. Although it looks similar to M3, its buttons may be different from M3. The system firmware I am currently using may have been modified by someone else, or it may have been an error during the modification, causing me to be unable to press the left and right buttons simultaneously with the B key.

And the screen driver of RS77 also needs to be adapted. The color and direction of the power on are opposite, and it was not normal after entering the system. After I modified the options.cfg in MIAN, it became normal

M3 should not have this issue because RS77 is a different model and it has an additional cross direction key compared to M3, and the buttons may also be different. Because I am using a kernel that has been modified by someone else to adapt to RS77, it is not an official kernel, so even if I modify the M3 kernel, I cannot use it normally.

[geek-sc]

Thank you very much, but currently, it seems inappropriate to directly modify the M3 buttons. It is indeed necessary to re adapt to the RS77 model, as I have tested using the M3 button kernel directly. RS77 cannot use the buttons properly and is not compatible.

Ok, this require to add support for RS-77 into official miyoo kernel first, so I'm closing this PR
