This has been moved to the reg property where it belongs for quite some time. The range has been unused by the kernel since then and with kernel 4.4 it's flagged as an unparsable range, as it does not comply to the PCI ranges DT binding.

Currently it is not possible to have HDMI and LVDS working simultaneously, because both ports try to use PLL5. Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be driven from independent sources. With this change the LDB pixel clock goes to 68.57 MHz, which is still within the valid range for the displays supported by the Ventana boards.

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.

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 c3ecef21 ("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.

The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

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.
