Configure ip-polling register to enable polling for all voltage monitor channels. This enables reading the voltage values for all inputs other than just input 0. Signed-off-by: Eliav Farber <farbere@xxxxxxxxxx> --- V3 -> V2: - Move configuration of ip-polling register from previous patch to a separate commit. V4 -> V3: - Replace GENMASK(pvt->c_num - 1, 0) with (BIT(pvt->c_num) - 1). drivers/hwmon/mr75203.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/drivers/hwmon/mr75203.c b/drivers/hwmon/mr75203.c index 69f38c05b02d..5f2b11a2bf5f 100644 --- a/drivers/hwmon/mr75203.c +++ b/drivers/hwmon/mr75203.c @@ -388,6 +388,19 @@ static int pvt_init(struct pvt_device *pvt) if (ret) return ret; + val = (BIT(pvt->c_num) - 1) | VM_CH_INIT | + IP_POLL << SDIF_ADDR_SFT | SDIF_WRN_W | SDIF_PROG; + ret = regmap_write(v_map, SDIF_W, val); + if (ret < 0) + return ret; + + ret = regmap_read_poll_timeout(v_map, SDIF_STAT, + val, !(val & SDIF_BUSY), + PVT_POLL_DELAY_US, + PVT_POLL_TIMEOUT_US); + if (ret) + return ret; + val = CFG1_VOL_MEAS_MODE | CFG1_PARALLEL_OUT | CFG1_14_BIT | IP_CFG << SDIF_ADDR_SFT | SDIF_WRN_W | SDIF_PROG; -- 2.37.1
