2009-11-22omap3: zoom: Drop i2c-1 speed to 2400vikram pandita
The I2C-1 bus frequency on zoom2/zoom3/sdp3630 should be 2.4 MHz. The speed is limited by TWL5030/GAIA; a higher speed could lead to errors on the interface. The maximum I2C speed depends on the system clock for GAIA: 2.2 MHz (sys-clk = 19.2 MHz) 2.4 MHz (sys-clk = 26 MHz) 2.9 MHz (sys-clk = 38.4 MHz) For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz and hence choose 2.4Mhz for I2C1 bus speed Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-11-22omap3: zoom: rename zoom2 name to generic zoomvikram pandita
Replace zoom2 with zoom name in board-zoom-peripherals.c file and board-zoom-debugboard.c. Create mach/board-zoom.h. This file has functions reused for boards: Zoom2/Zoom3/sdp3630. Hence have all functions commonly named as zoom Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-11-22omap3: zoom: split board file for software reusevikram pandita
Split zoom2 board file into a base board file and a board-zoom-peripherals.c file. That way the same peripherals file can be reused for zoom3 and sdp3630 in addition to zoom2. Also remove unused struct omap_board_config_kernel entry. NOTE: Keep the twl4030_madc_platform_data and twl4030_platform_data entries in board-zoom2.c to avoid merge conflicts with the pending patches in MFD tree. These entries will be removed later as a fix. Following list shows the commonality across the three platforms and hence the case for software reuse: Peripheral zoom2 zoom3 sdp3630 --------------------------------------- Ethernet smsc smsc smc NOR n/a n/a B Onenand n/a n/a B HDMI A A B (present on different i2c) NAND A A A (same nand) SDRAM A A A (same sdram) Keypad A A A (same twl) Camera A A A (same sensor can be mounted) LCD Display A A A (same wvga display) OPPs A A A (same chip feature) Audio A A A (same audio via twl5030) Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
