comments:
- CMT0/1
- prototype patches exist, clocksouce-switch test fails for CMT3, needs investigation
- the issue with clearing CMCNT happens on V3U as well, Gen3 seems not affected
- moving the issue to a seperate task
- enablement patches sent out
- patches merged
- done
- HSCIF
- HSCIF 0+1 can be muxed to FTDI chips, HSCIF3 to MSIOF headers using an external FTDI, HSCIF2 maybe via unpopulated I2C header
- all HSCIFs could be tested, patches sent
- patch to switch from SCIF3 to HSCIF0 was dropped because it won't work with all firmware revisions
- all other patches merged
- done
- MSIOF
- MSIOF0+2 work. MSIOF1+3 can't be tested because they are parallel with the FTDI serial for debug
- enablement patches sent
- concluded that MSIOF will be added to S4-8 DTSI file but not to Spider board because the voltage selection is unclear
- sent v2 of DTSI addition
- merged
- done
- RPC
- not for upstream because RPC shall only be accessed via OPTEE. See BSP commit 1f83a133b853138fad712d0a08a7689aac1e0183 ("Disable SPI flash via RPC")
- done
- SCIF
- SCIF 0+3 can be muxed to FTDI chips, SCIF1 to MSIOF headers using an external FTDI, SCIF4 maybe via unpopulated I2C header
- all SCIFs could be tested, patches sent
- patches merged
- done
- SD/MMC
- eMMC enabled and works, microSD enabled but still needs testing
- first patches sent, only final DTS addition kept until testing is done
- SD0H support was missing, resend needed
- eMMC works but is too slow compared to BSP, investigation needed
- microSD fails the same way the BSP does
- Shimoda-san researched that this is because SW6 needs to select the proper voltage
- SW is under the heat sink, though. So, for upstream only eMMC is desired
- resend patches to enable eMMC only
- slower speed than BSP moved to separate task
- slower speed was because of wrong kernel config, upstream kernel is actually faster
- SD0H patches sent out
- patches merged
- done
- THS/CIVM
- first version sent
- patch to improve logging needed more versions but we now came to a conclusion
- binding documentation needed more versions to handle the differences between all SoCs
- all patches merged
- done
- TMU
- probably possible; pinmux to TCLK1-4 and check via non-populated I2C header on breakout board
- enablement patches sent out
- all patches merged
- done
- all other devices are in the control domain which we do not handle. Only the application domain is our job.
