Hi,

Almost looks good to me. I add some comments.

On 21. 5. 31. 오후 10:34, Stephan Gerhold wrote:

SM5504 is another MUIC from Silicon Mitus that is fairly similar
to SM5502. They seem to use the same register set, but:

- SM5504 has some additional bits in SM5502_REG_CONTROL
- SM5504 has a quite different set of interrupts
- SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7)

Overall it's minor and we can support this using the existing
enum sm5502_types plus a few switch/if statements.

Changes in v2: Fix warning: cast to smaller integer type 'enum sm5502_types'
from 'const void *' [-Wvoid-pointer-to-enum-cast]
reported by kernel test robot

Interestingly enough the register set (and especially the interrupts)
also look *very* similar to Richtek RT8973A (extcon-rt8973a) but
I didn't investigate this further.

Note that the changes in this patch are mostly based on guesswork
based on a SM5504 driver from Nitin Chaudhary [1] used in some Samsung
vendor kernels, since I was not able to find a public datasheet for SM5504.

ditto. Better to add 'parse_irq' function pointer into struct sm5502_muic_info. And use 'info->parse_irq' instead of this.
