From e933ec7c4ebd7e7daaad67b22e5f4a9a0ab102ea Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Thu, 17 Jun 2010 15:48:43 -0700 Subject: OMAP1: PM: add simple runtime PM layer to manage clocks On OMAP1, we do not have omap_device + omap_hwmod to manage the device-specific idle, enable and shutdown. Instead, just enable/disable device clocks automatically at the runtime PM level. This allows drivers to not have any OMAP1 specific clock management and allows them to simply use the runtime PM API to manage clocks.

It also adds in the gpio-keys entries for the front directional keys and selector and the cursor keys on the slide-out keyboard, and gpio-leds support for the LEDs attached to the htcpld. Additionally, SPI bus support (using the spi100k driver) and touchscreen support (using the ads7846 driver) were added.

Three devices are declared: SoC camera, OMAP1 camera interface and OV6650 sensor. Default 12MHz clock has been selected for driving the sensor. Pixel clock has been limited to get reasonable frame rates, not exceeding the board capabilities. Since both devices (interface and sensor) support both pixel clock polarities, decision on polarity selection has been left to drivers. Interface GPIO line has been found not functional, thus not configured.
