   logic_pio: Build into a library (2019-10-28 20:46:05 +0800)

----------------------------------------------------------------
ARM64: hisi: SoC driver updates for 5.5

- check the LOGIC_PIO_INDIRECT region ops at registration instead of
   in the IO port accessors to optimise the lib/ligic_pio.c

- add the hisi LPC driver to the build test for the other architectures
   by updating the hisi LPC Kconfig and adding a dummy PIO_INDIRECT_SIZE

- clean the sparse complains of the hisi LPC driver

- build logic_pio into a lib to avoid including in the vmlinux when not
   referenced

----------------------------------------------------------------
John Garry (5):
       lib: logic_pio: Enforce LOGIC_PIO_INDIRECT region ops are set at 
registration
       logic_pio: Define PIO_INDIRECT_SIZE for !CONFIG_INDIRECT_PIO
       bus: hisi_lpc: Clean some types
       bus: hisi_lpc: Expand build test coverage

Hi xuwei,

kbuild bot is reporting a build failure for this patch:

         GCC_VERSION=7.4.0 make.cross ARCH=parisc

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <lkp@intel.com>

All errors (new ones prefixed by >>):

    drivers//bus/hisi_lpc.c: In function 'hisi_lpc_target_in':
 >> drivers//bus/hisi_lpc.c:137:2: error: implicit declaration of 
function 'readsb'; did you mean 'readb'? 
[-Werror=implicit-function-declaration]
      readsb(lpcdev->membase + LPC_REG_RDATA, buf, opcnt);
      ^~~~~~
      readb
    drivers//bus/hisi_lpc.c: In function 'hisi_lpc_target_out':

      writesb(lpcdev->membase + LPC_REG_WDATA, buf, opcnt);
      ^~~~~~~
      writeb
    cc1: some warnings being treated as errors

vim +137 drivers//bus/hisi_lpc.c

It seems that parisc has no definition for {read/write}sb().

I audited io.h for all architectures, and it seems that 3 in total would 
not define {read/write}sb(): hexagon, parisc, alpha

So these don't include asm-generic/io.h and do not define their own 
version of read/writesb(). I'm thinking that they should do.

Quite frustrating.

I guess that this now can't be picked up now.

To fix, I suppose that I need not expand test coverage to these archs 
for now, and then also add {read/write}sb() definitions for these archs. 
Or they can include asm-generic.h, but this may create more problems.

Arnd, Any opinion on this?

Thanks,
John

Hi ARM-SoC team,

Sorry there are some build failures for this pull on the parisc, hexagon 
and alpha architectures.
Please ignore this pull request.
We will fix them and resend.
Thanks!

Best Regards,
Wei
