2015-12-22ARM: dts: TS-4800: use weim IP to map the FPGADamien Riegel
Previously, the device tree mapped the FPGA like any other IPs inside the SoC, but it is actually mapped through the WEIM (Wireless External Interface Module). This patch updates the device tree to make use of it. About the timings: in the image provided by the manufacturer, only CS0GCR1 is changed. The other values are the default ones, but the WEIM bindings expect them to be all explicitly set in the device tree, so I just put the default values in the dt.

2015-12-11ARM: dts: vf610: use reset values for L2 cache latenciesStefan Agner
Linux on Vybrid used several different L2 latencies so far, none of them seem to be the right ones. According to the application note AN4947 ("Understanding Vybrid Architecture"), the tag portion runs on CPU clock and is inside the L2 cache controller, whereas the data portion is stored in the external SRAM running on platform clock. Hence it is likely that the correct value requires a higher data latency then tag latency. These are the values which have been used so far: - The mainline values: arm,data-latency = <1 1 1>; arm,tag-latency = <2 2 2>; Those values have lead to problems on higher clocks. They look like a poor translation from the reset values (missing +1 offset and a mix up between tag/latency values). - The Linux 3.0 (SoC vendor BSP) values (converted to DT notation): arm,data-latency = <4 2 3> arm,tag-latency = <4 2 3> The cache initialization function along with the value matches the i.MX6 code from the same kernel, so it seems that those values have just been copied. - The Colibri values: arm,data-latency = <2 1 2>; arm,tag-latency = <3 2 3>; Those were a mix between the values of the Linux 3.0 based BSP and the mainline values above. - The SoC Reset values (converted to DT notation): arm,data-latency = <3 3 3>; arm,tag-latency = <2 2 2>; So far there is no official statement on what the correct values are. See also the related Freescale community thread: https://community.freescale.com/message/579785#579785 For now, the reset values seem to be the best bet. Remove all other "bogus" values and use the reset value on vf610.dtsi level. Signed-off-by: Stefan Agner <stefan@agner.ch> Cc: <stable@vger.kernel.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2015-12-02ARM: dts: vf610: fix clock definition for SAI2Stefan Agner
So far, only the bus clock has been assigned, but in reality the SAI IP has for clock inputs. The driver has been updated to make use of the additional clock inputs by c3ecef21c3f2 ("ASoC: fsl_sai: add sai master mode support"). Due to a bug in the clock tree, the audio clock has been enabled none the less by the specified bus clock (see "ARM: imx: clk-vf610: fix SAI clock tree"), which made master mode even without the proper clock assigned working. This patch completes the clock definition for SAI2. On Vybrid, only two MCLK out of the four options are available (the first being the bus clock itself). See chapter 8.10.1.2.3 of the Vybrid Reference manual ("SAI transmitter and receiver options for MCLK selection"). Note: The audio clocks are only required in master mode.

2015-11-23ARM: imx: add platform irq type setting in gpcAnson Huang
GPC irq domain is a child domain of GIC, now all of platform irqs are inside GPC domain, during the module populate, all devices irq should have correct type setting in GIC, however, there is no .irq_set_type callback setting in GPC, so the irq_set_type will be skipped and cause all irqs' type in /proc/interrupt are "edge" which mismatch with irq type setting in dtb file. Since GPC has no irq type setting, so just tell kernel to use irq_chip_set_type_parent.
