[PATCH v3 15/20] GPIO: OMAP: Use readl in irq_handler for all access

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

 



From: Charulatha V <charu@xxxxxx>

Even when bank->width is 16, all the OMAP1 registers are 4-byte aligned, so just
use a 4-byte read.  The 'enabled' mask is already taking care to mask for bank width.
