From ba51bdd306a21ab0fabbea3a92541af0ee9fb8f6 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Wed, 7 Nov 2012 08:44:55 +0900 Subject: gpio: samsung: Skip registration if pinctrl driver is present on EXYNOS4X12 This patch modifies the Samsung GPIO driver to check for pinctrl driver presence earlier and use generic matching instead of a single compatible value. This allows us to fix warning about unrecognized SoC in case of EXYNOS4X12, which is not supported by this driver.

And it adds the effort on supporting multiple platform. So remove it. The assumption is that nobody will miss this support. If you are reading this text because you actually require pxa95x support on a new kernel, we can work out a way to revert this patch or add support to the mmp platform.

The appropriate pieces are built based on whether SPI and/or I2C is/are enabled. However, it was only checking if I2C was built-in, never if it was built as a module. This patch checks for either since building both this driver and I2C as modules is possible. Signed-off-by: Daniel M.
