From cb07d74e2e0c0a41533b6bcd551af9bf2ebcf2bc Mon Sep 17 00:00:00 2001 From: Markus Niebel Date: Fri, 18 Jul 2014 16:52:44 +0200 Subject: Add TQ Systems TQMa6 board support This patch adds the changes to boards.cfg and the board directory under board/tqc. TQMa6 is a family of modules based on Freescale i.MX6. It consists of TQMa6Q (i.MX6 Quad), TQMa6D (i.MX6 Dual) featuring eMMC, and 1 GiB DDR3 TQMa6S (i.MX6 Solo) featuring eMMC and 512 MiB DDR3 The modules need a baseboard. Initially the MBa6x starterkit mainboard is supported. To easy support for other mainboards the functionality is splitted in one file for the module (tqma6.c) and one file for the baseboard (tqma6_ mba6). The modules can be boot from eMMC (on USDHC3) and SPI flash. The following features are supported: - MMC: eMMC on module (on USDHC3) and SD-card (on MBa6x mainboard) - Ethernet: RGMII using micrel KSZ9031 phy on MBa6x mainboard for TQMa6 module. The phy needs special configurations for the pad skew registers to adjust for the signal routing. Also support for standard ethernet commands and uppdate via tftp. - SPI: ECSPI1 with bootable serial flash on module and two additional chip selects on MBa6x - I2C: This patch adds support for the I2C busses on the TQMa6 modules (I2C3) and MBa6x baseboards (I2C1). The LM75 temperature sensors on TQMa6 and MBa6x are also configured. - USB: high speed host 1 on MBa6x and support for USB storage - PMIC: support for pfuze 100 on TQMa6 Signed-off-by: Markus Niebel --- board/tqc/tqma6/clocks.cfg | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 board/tqc/tqma6/clocks.cfg (limited to 'board/tqc/tqma6/clocks.cfg') diff --git a/board/tqc/tqma6/clocks.cfg b/board/tqc/tqma6/clocks.cfg new file mode 100644 index 0000000000..d9dd273a2b --- /dev/null +++ b/board/tqc/tqma6/clocks.cfg @@ -0,0 +1,24 @@ +/* + * Copyright (C) 2013 Boundary Devices + * Copyright (C) 2013, 2014 Markus Niebel + * + * SPDX-License-Identifier: GPL-2.0+ + * + * Refer doc/README.imximage for more details about how-to configure + * and create imximage boot image + */ + +/* set the default clock gate to save power */ +DATA 4, CCM_CCGR0, 0x00C03F3F +DATA 4, CCM_CCGR1, 0x0030FC03 +DATA 4, CCM_CCGR2, 0x0FFFC000 +DATA 4, CCM_CCGR3, 0x3FF00000 +DATA 4, CCM_CCGR4, 0x00FFF300 +DATA 4, CCM_CCGR5, 0x0F0000C3 +DATA 4, CCM_CCGR6, 0x000003FF + +/* enable AXI cache for VDOA/VPU/IPU */ +DATA 4, MX6_IOMUXC_GPR4, 0xF00000CF +/* set IPU AXI-id0 Qos=0xf(bypass) AXI-id1 Qos=0x7 */ +DATA 4, MX6_IOMUXC_GPR6, 0x007F007F +DATA 4, MX6_IOMUXC_GPR7, 0x007F007F -- cgit
