Message-ID: <1369812944-685-1-git-send-email-oleksandr.dmytryshyn@ti.com> Date: Wed, 29 May 2013 10:35:43 +0300 From: Oleksandr Dmytryshyn <oleksandr.dmytryshyn@...com> To: Tony Lindgren <tony@...mide.com>, Wolfram Sang <wsa@...-dreams.de> CC: <linux-omap@...r.kernel.org>, <linux-i2c@...r.kernel.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH 0/1] i2c: omap: correct usage of the interrupt enable register Interrupts from i2c controller are enabled while i2c bus is in the suspend mode (I2C_IE register doesn't equals to 0). Starting from the OMAP chips with version2 registers scheme there are 2 registers (I2C_IRQENABLE_SET and I2C_IRQENABLE_CLR) to manage interrupts instead of the older OMAP chips old scheme which have only one register (I2C_IE). Now for enabling interrupts we must use I2C_IRQENABLE_SET register and for disabling interrupts we must use I2C_IRQENABLE_CLR register. Next patch fixes it. Patch is based on: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git tag: v3.10-rc2 Verified on OMAP4430.
