* i2c: iproc: Add Broadcom iProc I2C DriverRay Jui2015-02-171-0/+37
| | | | | | | | | | | | | | Add initial support to the Broadcom iProc I2C controller found in the iProc family of SoCs. The iProc I2C controller has separate internal TX and RX FIFOs, each has a size of 64 bytes. The iProc I2C controller supports two bus speeds including standard mode (100kHz) and fast mode (400kHz) Signed-off-by: Ray Jui <rjui@broadcom.com> Reviewed-by: Scott Branden <sbranden@broadcom.com> Reviewed-by: Kevin Cernekee <cernekee@chromium.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

| | | | | | | | | | | | | clock-frequency property is meant to control the bus frequency for i2c bus drivers, but it was incorrectly used to specify i2c controller input clock frequency. Introduce new attribute, opencores,ip-clock-frequency, that specifies i2c controller clock frequency and make clock-frequency attribute compatible with other i2c drivers. Maintain backwards compatibility in case opencores,ip-clock-frequency attribute is missing. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* of: i2c: Add i2c-mux-idle-disconnect DT property to PCA954x mux driverAlexander Sverdlin2015-01-231-0/+3
| | | | | | | | | | | Add i2c-mux-idle-disconnect device tree property to PCA954x mux driver. The new property forces the multiplexer to disconnect child buses in idle state. This is used, for example, when there are several multiplexers on the same bus and the devices on the underlying buses might have same I2C addresses.

* i2c: rk3x: Account for repeated start time requirementDoug Anderson2015-01-131-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Rockchip I2C the controller drops SDA low slightly too soon to meet the "repeated start" requirements. >From my own experimentation over a number of rates: - controller appears to drop SDA at .875x (7/8) programmed clk high. - controller appears to keep SCL high for 2x programmed clk high. The first rule isn't enough to meet tSU;STA requirements in Standard-mode on the system I tested on. The second rule is probably enough to meet tHD;STA requirements in nearly all cases (especially after accounting for the first), but it doesn't hurt to account for it anyway just in case. Even though the repeated start requirement only need to be accounted for during a small part of the transfer, we'll adjust the timings for the whole transfer to meet it. I believe that adjusting the timings in just the right place to switch things up for repeated start would require several extra interrupts and that doesn't seem terribly worth it. With this change and worst case rise/fall times, I see 100kHz i2c going to ~85kHz. With slightly optimized rise/fall (800ns / 50ns) I see i2c going to ~89kHz. Fast-mode isn't affected much because tSU;STA is shorter relative to tHD;STA there. As part of this change we needed to account for the SDA falling time. The specification indicates that this should be the same, but we'll follow Designware's lead and add a binding. Note that we deviate from Designware and assign the default SDA falling time to be the same as the SCL falling time, which is incredibly likely.

* i2c: rk3x: fix bug that cause measured high_ns doesn't meet I2C specificationaddy ke2015-01-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of clock cycles to be written into the CLKDIV register that determines the I2C clk high phase includes the rise time. So to meet the timing requirements defined in the I2C specification which defines the minimal time SCL has to be high, the rise time has to taken into account. The same applies to the low phase with falling time. In my test on RK3288-Pink2 board, which is not an upstream board yet, if external pull-up resistor is 4.7K, rise_ns is about 700ns. So the measured high_ns is about 3900ns, which is less than 4000ns (the minimum high_ns in I2C specification for Standard-mode). To fix this bug min_low_ns should include fall time and min_high_ns should include rise time. This patch merged the patch from chromium project which can get the rise and fall times for signals from the device tree. This allows us to more accurately calculate timings. see: https://chromium-review.googlesource.com/#/c/232774/ Signed-off-by: Addy Ke <addy.ke@rock-chips.com> Reviewed-by: Doug Anderson <dianders@chromium.org> Tested-by: Doug Anderson <dianders@chromium.org> [wsa: fixed a typo in the docs] Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

| | * | clk: sunxi: Implement A31 PLL6 as a divs clock for 2x outputChen-Yu Tsai2014-11-231-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some clock modules on the A31 use PLL6x2 as one of their inputs. This patch changes the PLL6 implementation for A31 to a divs clock, i.e. clock with multiple outputs that have different dividers. The first output will be the normal PLL6 output, and the second will be PLL6x2. This patch fixes the PLL6 N factor in the clock driver, and removes any /2 dividers in the PLL6 factors clock part. The N factor counts from 1 to 32, mapping to values 0 to 31, as shown in the A31 manual. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

Also there is a bus clock for a ARM CCI400 module. As far as I can tell, the GT bus and CCI400 bus clock must be protected. This patch adds driver support for peripheral related PLLs and bus clocks on the A80.
