From mboxrd@z Thu Jan 1 00:00:00 1970 From: snijsure@grid-net.com (Subodh Nijsure) Date: Thu, 17 May 2012 16:03:43 -0700 Subject: Issues when running DT enabled kernel on iMX28 from linux-next Message-ID: <4FB583CF.2080801@grid-net.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Should one be able to run top of the linux-next on MX28 EVK hardware with DT support enabled? I have attached boot log I see when I try to do that. Further if one enables, CONFIG_MTD_NAND_GPMI_NAND=y CONFIG_MTD_NAND_PLATFORM=y code in drivers/mtd/nand/gpmi-nand/gpmi-nand.c doesn't compile because of this code: pinctrl = devm_pinctrl_get_select_default(&pdev->dev); if (IS_ERR(pinctrl)) { ret = PTR_ERR(pinctrl); goto exit_pin; } -Subodh [ 0.000000] Booting Linux on physical CPU 0 [ 0.000000] Linux version 3.4.0-rc7-next-20120516-dirty (snijsure at subodh-desktop) (gcc version 4.3.3 (Sour cery G++ Lite 2009q1-203) ) #3 Thu May 17 15:40:42 PDT 2012 [ 0.000000] CPU: ARM926EJ-S [41069265] revision 5 (ARMv5TEJ), cr=00053177 [ 0.000000] CPU: VIVT data cache, VIVT instruction cache [ 0.000000] Machine: Freescale i.MX28 (Device Tree), model: Freescale i.MX28 Evaluation Kit [ 0.000000] Memory policy: ECC disabled, Data cache writeback [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
