From b8453d4ee9e24c6590dd0eecbab1c3cc2028317f Mon Sep 17 00:00:00 2001 From: Wenyou Yang Date: Mon, 9 May 2016 14:51:19 +0800 Subject: [PATCH 1/3] ARM: dts: at91: sama5d2: use "atmel,sama5d3-nfc" compatible for nfc An error in documentation of the NAND Flash Controller (NFC) led to choose another compatibility string for sama5d2 with an impact on the NAND flash ready/busy information. It was producing the error message: atmel_nand 80000000.nand: Time out to wait for interrupt: 0x08000000 and had an impact on performance. So, switch back to the classical "atmel,sama5d3-nfc" compatibility string for this SoC which gives the proper ready/busy bit information. The NAND flash driver will be updated to remove the support for this different implementation.

This was working fine thanks to the page granularity of ioremap(), but started to fail when we switched to syscon/regmap, because regmap is making sure that all accesses are falling into the reserved range.
