Add driver for pin controller in Low Power Audio SubSystem (LPASS). The driver is similar to SM8250 LPASS pin controller, with difference in one new pin (gpio14).quoted
< LPI_MUX_swr_tx_data2, 54d52 < static int gpio14_pins[] = { 14 }; 71d68 < PINCTRL_PIN(14, "gpio14"), 75c72 < static const char * const swr_tx_data_groups[] = { "gpio1", "gpio2", "gpio5", "gpio14" }; ---quoted
static const char * const swr_tx_data_groups[] = { "gpio1", "gpio2", "gpio5" };111d107 < LPI_PINGROUP(14, 6, swr_rx_data, _, _, _), I really think adding just these pin14 entries to the 8250 driver would be a good idea..I could extend arrays with gpio14 and pass array size -1 to sm8250 variant and full size to sm8350. However the difference will be in: -static const char * const swr_tx_data_groups[] = { "gpio1", "gpio2", "gpio5" }; +static const char * const swr_tx_data_groups[] = { "gpio1", "gpio2", "gpio5", "gpio14" }; I cannot create here variant "swr_tx_data_groups_sm8350" because the name is used in macros. Using bigger (with gpio14) group for sm8250 should work, because there is no gpio14, but produces difference in the controller: -/sys/kernel/debug/pinctrl/33c0000.pinctrl/pinmux-functions:function 18: swr_tx_data, groups = [ gpio1 gpio2 gpio5 ] +/sys/kernel/debug/pinctrl/33c0000.pinctrl/pinmux-functions:function 18: swr_tx_data, groups = [ gpio1 gpio2 gpio5 gpio14 ] Therefore I will go with separate drivers.
