[PATCH v4 4/6] serial: 8250_em: Update port type as PORT_16750

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The UART IP found on {RZ/V2M, EMMA mobile} SoC is Register-compatible
with the general-purpose 16750 UART chip. This patch updates port type
from 16550A->16750 and also enables 64-bytes fifo support.

v3->v4:
 * Both {RZ/V2M, EMMA mobile} SoC is Register-compatible
   with the general-purpose 16750 UART chip. So started using
   generic compatible and removed struct serial8250_em_hw_info.
 * Removed Rb tag from Ilpo as it is new change.
v2->v3:
 * Replaced of_device_get_match_data()->device_get_match_data().
 * Replaced of_device.h->property.h
 * Dropped struct serial8250_em_hw_info *info from priv and started
   using a local variable info in probe().
 * Retained Rb tag from Ilpo as changes are trivial.
v2:
 * New patch
