According to datasheet, i.MX6Q has setpoint of 852MHz which is exclusive with 996MHz, the fuse map of speed_grading defines the max speed of ARM, here we add this 852MHz setpoint opp info, kernel will check the speed_grading fuse and remove all illegal setpoints. Signed-off-by:

Apply the same work-around for i.MX 6D/Q erratum 006687 as used for Sabre Lite for the Wandboard Dual / Quad. Like on the Sabre Lite, GPIO6 is used as a power down output for camera expansion boards. However, these expansion boards do not work with mainline yet anyway. Tested on a Wandboard Quad. Before the patch: root@arm:~# ping -q -f -c 10000 192.168.2.1 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data. === 192.168.2.1 ping statistics === 10000 packets transmitted, 10000 received, 0% packet loss, time 97363ms rtt min/avg/max/mdev = 0.290/9.586/10.198/1.432 ms, pipe 2, ipg/ewma 9.737/9.672 ms After the patch: root@arm:~# ping -q -f -c 10000 192.168.2.1 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data. === 192.168.2.1 ping statistics === 10000 packets transmitted, 10000 received, 0% packet loss, time 4810ms rtt min/avg/max/mdev = 0.246/0.355/0.863/0.044 ms, ipg/ewma 0.481/0.319 ms Signed-off-by:

This works around a hardware bug. From "Chip Errata for the i.MX 6Dual/6Quad" ERR006687 ENET: Only the ENET wake-up interrupt request can wake the system from Wait mode. The ENET block generates many interrupts. Only one of these interrupt lines is connected to the General Power Controller (GPC) block, but a logical OR of all of the ENET interrupts is connected to the General Interrupt Controller (GIC). When the system enters Wait mode, a normal RX Done or TX Done does not wake up the system because the GPC cannot see this interrupt. This impacts performance of the ENET block because its interrupts are serviced only when the chip exits Wait mode due to an interrupt from some other wake-up source. Before this patch, ping times of a Sabre Lite board are quite random: ping 192.168.0.13 -i.5 -c5 PING 192.168.0.13 (192.168.0.13) 56(84) bytes of data. 64 bytes from 192.168.0.13: icmp_req=1 ttl=64 time=15.7 ms 64 bytes from 192.168.0.13: icmp_req=2 ttl=64 time=14.4 ms 64 bytes from 192.168.0.13: icmp_req=3 ttl=64 time=13.4 ms 64 bytes from 192.168.0.13: icmp_req=4 ttl=64 time=12.4 ms 64 bytes from 192.168.0.13: icmp_req=5 ttl=64 time=11.4 ms === 192.168.0.13 ping statistics === 5 packets transmitted, 5 received, 0% packet loss, time 2004ms rtt min/avg/max/mdev = 11.431/13.501/15.746/1.508 ms ____________________________________________________ After this patch: ping 192.168.0.13 -i.5 -c5 PING 192.168.0.13 (192.168.0.13) 56(84) bytes of data. 64 bytes from 192.168.0.13: icmp_req=1 ttl=64 time=0.120 ms 64 bytes from 192.168.0.13: icmp_req=2 ttl=64 time=0.175 ms 64 bytes from 192.168.0.13: icmp_req=3 ttl=64 time=0.169 ms 64 bytes from 192.168.0.13: icmp_req=4 ttl=64 time=0.168 ms 64 bytes from 192.168.0.13: icmp_req=5 ttl=64 time=0.172 ms === 192.168.0.13 ping statistics === 5 packets transmitted, 5 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.120/0.160/0.175/0.026 ms ____________________________________________________ Also, apply same change to imx6qdl-nitrogen6x. This change may not be appropriate for all boards. Sabre Lite uses GPIO6 as a power down output for a ov5642 camera. As this expansion board does not yet work with mainline, this is not yet a conflict. It would be nice to have an alternative fix for boards where this is a problem. For example Sabre SD uses GPIO6 for I2C3_SDA. It also has long ping times currently. But cannot use this fix without giving up a touchscreen. Its ping times are also random. ping 192.168.0.19 -i.5 -c5 PING 192.168.0.19 (192.168.0.19) 56(84) bytes of data. 64 bytes from 192.168.0.19: icmp_req=1 ttl=64 time=16.0 ms 64 bytes from 192.168.0.19: icmp_req=2 ttl=64 time=15.4 ms 64 bytes from 192.168.0.19: icmp_req=3 ttl=64 time=14.4 ms 64 bytes from 192.168.0.19: icmp_req=4 ttl=64 time=13.4 ms 64 bytes from 192.168.0.19: icmp_req=5 ttl=64 time=12.4 ms === 192.168.0.19 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 12.451/14.369/16.057/1.316 ms Signed-off-by:

This impacts performance of the ENET block because its interrupts are serviced only when the chip exits Wait mode due to an interrupt from some other wake-up source. Adding MX6QDL_PAD_GPIO_6__ENET_IRQ is the 1st step to workaround this problem. The input reg is set to 0x3c to set IOMUX_OBSRV_MUX1 to ENET_IRQ. The mux reg value is 0x11, so that the observable mux is routed to this pin and to the gpio controller(sion bit). These magic values come from Ranjani Vaidyanathan's patch: "ENGR00257847-1 MX6Q/DL-Fix Ethernet performance issue when WAIT mode is active" Signed-off-by:

Instead of calling the regulator for the ARM core as 'cpu', let's rename it as 'vddarm', so that we keep a better consistency with the other internal regulators: vdd1p1: 800 <--> 1375 mV at 1100 mV vdd3p0: 2800 <--> 3150 mV at 3000 mV vdd2p5: 2000 <--> 2750 mV at 2400 mV vddarm: 725 <--> 1450 mV at 1150 mV vddpu: 725 <--> 1450 mV at 1150 mV vddsoc: 725 <--> 1450 mV at 1200 mV Signed-off-by:
