This patchset adds basic support for the Qualcomm Snapdragon 805 APQ8084 SoC.
The first two patches add device-tree files for the SoC and the board, the
third adds a board compatible string to the DT machine descriptor.
The last one adds information about the low-level debug UART base address
to the DEBUG_QCOM_UARTDM Kconfig help section introduced by [1].
Tested on APQ8084-MTP board.
Changes from v1:
- Remove the interrupts property from the l2-cache node as it is still not
accepted (suggested by Stephen Boyd)
- Move the timer node out of the soc container (suggested by Stephen Boyd)
- Add just "qcom,apq8084" in the board machine descriptors to cover other
future boards based on apq8084 (suggested by Kumar Gala)
- Change the last patch (debug UART) to just add info about the SoC PHYS/VIRT
addresses. Requires [1]. (suggestions by Arnd Bergmann and Ivan Ivanov)

The uart dts definition depends on clocks, but the DEBUG_LL support does not. And the DEBUG_LL support is already there as it is common with other SoCs. I am sorry, but i don't see dependency between the dts definition and this patch. Could you explain please? Thanks, Georgi ^ permalink raw reply [flat|nested] 11+ messages in thread

IMHO the dependancy is that DEBUG_LL uses the uart device, and this is added when you add the dts. AFAIK there can arise problems with multi-platform kernels if the uart is not present. > > Thanks, > Georgi > -- motzblog.wordpress.com ^ permalink raw reply [flat|nested] 11+ messages in thread

Once DEBUG_LL is enabled you don't have multi-platform kernel anymore, so this should not be an issue here. Regards, Ivan ^ permalink raw reply [flat|nested] 11+ messages in thread
