[PATCH v2 0/3] Add __ioread32_copy() and use it

From: Stephen Boyd
Date: Thu Sep 17 2015 - 15:02:30 EST


The SMD driver is reading and writing chunks of data to iomem,
and there's an __iowrite32_copy() function for the writing part, but
no __ioread32_copy() function for the reading part. This series
adds __ioread32_copy() and uses it in two places. Andrew is on Cc in
case this should go through the -mm tree. Otherwise the target
of this patch series is SMD, so I've sent it to Andy.

Note this patch series relies on a previous patch on the list that
changes the readl() to __raw_readl() in the smd driver[1].

Changes since v1:
* Dropped weak from __ioread32_copy()

Stephen Boyd (3):
lib: iomap_copy: Add __ioread32_copy()
soc: qcom: smd: Use __ioread32_copy() instead of open-coding it
FIRMWARE: bcm47xx_nvram: Use __ioread32_copy() instead of open-coding
