From bd8eca2c0f5542c5b20b1c2cc506b8b8a46018df Mon Sep 17 00:00:00 2001

Subject: [PATCH] ath9k: use iowrite32 over __raw_writel
To: linux-wireless@vger.kernel.org
Cc: QCA ath9k Development <ath9k-devel@qca.qualcomm.com>,
Kalle Valo <kvalo@codeaurora.org>,
Hauke Mehrtens <hauke@hauke-m.de>,
Mathias Kresin <dev@kresin.me>,
Martin Blumenstingl <martin.blumenstingl@googlemail.com>
This patch changes the ath9k_pci_owl_loader to use the
same iowrite32 memory accessor that ath9k_pci is using
to communicate with the PCI(e) chip.
This will fix endian issues that came up during testing
with loaned AVM Fritz!Box 7360 (Lantiq MIPS SoCs + AR9287).
Fixes: 5a4f2040fd07 ("ath9k: add loader for AR92XX (and older) pci(e)")
