Subject: [PATCH v2 0/6] Add DW PCIe support for Exynos5433 SoCs
Date: Fri, 23 Oct 2020 09:57:38 +0200 [thread overview]
Message-ID: <20201023075744.26200-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20201023075754eucas1p2ee617893ba13493236814235c619bc56@eucas1p2.samsung.com
Dear All,
This patchset is a resurrection of the DW PCIe support for the Exynos5433
SoCs posted long time ago here: https://lkml.org/lkml/2016/12/26/6 and
later here: https://lkml.org/lkml/2017/12/21/296 .
In meantime the support for the Exynos5440 SoCs has been completely
dropped from mainline kernel, as those SoCs never reached the market. The
PCIe driver for Exynos5440 variant however has not been removed yet. This
patchset simply reworks it to support the Exynos5433 variant. The lack of
the need to support both variants significantly simplifies the driver
code.
Best regards,
Marek Szyprowski
v2:
- fixed issues in dt-bindings pointed by Krzysztof and Rob
v1: https://lore.kernel.org/linux-samsung-soc/20201019094715.15343-1-m.szyprowski@samsung.com/
- initial version of this resurrected patchset
