Increase ADC reference clock from 3MHz to 24MHz so that the sampling rates goes up from 100K samples per second to 800K samples per second on AM335x and AM437x SoC. Signed-off-by: Mugunthan V N <redacted> --- include/linux/mfd/ti_am335x_tscadc.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
Change looks okay though. For my own reference: Acked-for-MFD-by: Lee Jones [off-list ref]
