Jarkko Nikula b53548f9d9 spi: pxa2xx: Remove LPSS private register restoring during resume ... Intel LPSS private register restoring in spi-pxa2xx.c: pxa2xx_spi_resume() was added before there was no any other code restoring them. This was changed after following commits for previous and current LPSS platforms: c78b083066 ("ACPI / LPSS: custom power domain for LPSS") 41a3da2b8e ("mfd: intel-lpss: Save register context on suspend") However there is one caveat: There is no LPSS private register context save/restore for the Intel Lynxpoint in the Linux kernel code. I did some debugging on one Lynxpoint based device I have and on it the LPSS register context is not lost over suspend/resume cycle (s2idle). Which happens for instance on Intel Braswell. I'm speculating but I guess either firmware does it or the LPSS is kept always on Lynxpoint. Given that we haven't needed to implement Lynxpoint LPSS I2C or UART private register context save/restore over four years time I think we are safe to remove this LPSS private register restoring during resume here.
