From 0ad1fbc86045c2a27ff082c02344131be072699f Mon Sep 17 00:00:00 2001 From: eric miao Date: Wed, 2 Jan 2008 17:34:27 +0800 Subject: [PATCH] [ARM] pxa: remove un-used pxa3xx_mfp_set_xxx() functions pxa3xx_mfp_set_xxx() functions are originally provided for overwriting MFP configurations performed by pxa3xx_mfp_config(), the usage of such a dirtry trick is not recommended, since there is currently no user of these functions, they are safely removed Signed-off-by: eric miao Signed-off-by: Russell King --- arch/arm/mach-pxa/mfp.c | 111 --------------------------------- include/asm-arm/arch-pxa/mfp.h | 14 ----- 2 files changed, 125 deletions(-) diff --git a/arch/arm/mach-pxa/mfp.c b/arch/arm/mach-pxa/mfp.c index 436f96574964..785ae0ddb84f 100644 --- a/arch/arm/mach-pxa/mfp.c +++ b/arch/arm/mach-pxa/mfp.c @@ -96,117 +96,6 @@ void pxa3xx_mfp_write(int mfp, unsigned long val) spin_unlock_irqrestore(&mfp_spin_lock, flags); } -void pxa3xx_mfp_set_afds(int mfp, int af, int ds) -{ - uint32_t mfpr_off, mfpr_val; - unsigned long flags; - - BUG_ON(mfp >= MFP_PIN_MAX); - - spin_lock_irqsave(&mfp_spin_lock, flags); - mfpr_off = mfp_table[mfp].mfpr_off; - - mfpr_val = mfpr_readl(mfpr_off); - mfpr_val &= ~(MFPR_AF_MASK | MFPR_DRV_MASK); - mfpr_val |= (((af & 0x7) << MFPR_ALT_OFFSET) | - ((ds & 0x7) << MFPR_DRV_OFFSET)); - - mfpr_writel(mfpr_off, mfpr_val); - mfpr_sync(); - - spin_unlock_irqrestore(&mfp_spin_lock, flags); -} - -void pxa3xx_mfp_set_rdh(int mfp, int rdh) -{ - uint32_t mfpr_off, mfpr_val; - unsigned long flags; - - BUG_ON(mfp >= MFP_PIN_MAX); - - spin_lock_irqsave(&mfp_spin_lock, flags); - - mfpr_off = mfp_table[mfp].mfpr_off; - - mfpr_val = mfpr_readl(mfpr_off); - mfpr_val &= ~MFPR_RDH_MASK; - - if (likely(rdh)) - mfpr_val |= (1u << MFPR_SS_OFFSET); - - mfpr_writel(mfpr_off, mfpr_val); - mfpr_sync(); - - spin_unlock_irqrestore(&mfp_spin_lock, flags); -} - -void pxa3xx_mfp_set_lpm(int mfp, int lpm) -{ - uint32_t mfpr_off, mfpr_val; - unsigned long flags; - - BUG_ON(mfp >= MFP_PIN_MAX); - - spin_lock_irqsave(&mfp_spin_lock, flags); - - mfpr_off = mfp_table[mfp].mfpr_off; - mfpr_val = mfpr_readl(mfpr_off); - mfpr_val &= ~MFPR_LPM_MASK; - - if (lpm & 0x1) mfpr_val |= 1u << MFPR_SON_OFFSET; - if (lpm & 0x2) mfpr_val |= 1u << MFPR_SD_OFFSET; - if (lpm & 0x4) mfpr_val |= 1u << MFPR_PU_OFFSET; - if (lpm & 0x8) mfpr_val |= 1u << MFPR_PD_OFFSET; - if (lpm &0x10) mfpr_val |= 1u << MFPR_PS_OFFSET; - - mfpr_writel(mfpr_off, mfpr_val); - mfpr_sync(); - - spin_unlock_irqrestore(&mfp_spin_lock, flags); -} - -void pxa3xx_mfp_set_pull(int mfp, int pull) -{ - uint32_t mfpr_off, mfpr_val; - unsigned long flags; - - BUG_ON(mfp >= MFP_PIN_MAX); - - spin_lock_irqsave(&mfp_spin_lock, flags); - - mfpr_off = mfp_table[mfp].mfpr_off; - mfpr_val = mfpr_readl(mfpr_off); - mfpr_val &= ~MFPR_PULL_MASK; - mfpr_val |= ((pull & 0x7u) << MFPR_PD_OFFSET); - - mfpr_writel(mfpr_off, mfpr_val); - mfpr_sync(); - - spin_unlock_irqrestore(&mfp_spin_lock, flags); -} - -void pxa3xx_mfp_set_edge(int mfp, int edge) -{ - uint32_t mfpr_off, mfpr_val; - unsigned long flags; - - BUG_ON(mfp >= MFP_PIN_MAX); - - spin_lock_irqsave(&mfp_spin_lock, flags); - - mfpr_off = mfp_table[mfp].mfpr_off; - mfpr_val = mfpr_readl(mfpr_off); - - mfpr_val &= ~MFPR_EDGE_MASK; - mfpr_val |= (edge & 0x3u) << MFPR_ERE_OFFSET; - mfpr_val |= (!edge & 0x1) << MFPR_EC_OFFSET; - - mfpr_writel(mfpr_off, mfpr_val); - mfpr_sync(); - - spin_unlock_irqrestore(&mfp_spin_lock, flags); -} - void __init pxa3xx_mfp_init_addr(struct pxa3xx_mfp_addr_map *map) { struct pxa3xx_mfp_addr_map *p; diff --git a/include/asm-arm/arch-pxa/mfp.h b/include/asm-arm/arch-pxa/mfp.h index 7de234b0cca7..60fbed1b2e89 100644 --- a/include/asm-arm/arch-pxa/mfp.h +++ b/include/asm-arm/arch-pxa/mfp.h @@ -418,20 +418,6 @@ struct pxa3xx_mfp_pin { unsigned long pxa3xx_mfp_read(int mfp); void pxa3xx_mfp_write(int mfp, unsigned long mfpr_val); -/* - * pxa3xx_mfp_set_afds - set MFP alternate function and drive strength - * pxa3xx_mfp_set_rdh - set MFP release delay hold on/off - * pxa3xx_mfp_set_lpm - set MFP low power mode state - * pxa3xx_mfp_set_edge - set MFP edge detection in low power mode - * - * use these functions to override/change the default configuration - * done by pxa3xx_mfp_set_config(s) - */ -void pxa3xx_mfp_set_afds(int mfp, int af, int ds); -void pxa3xx_mfp_set_rdh(int mfp, int rdh); -void pxa3xx_mfp_set_lpm(int mfp, int lpm); -void pxa3xx_mfp_set_edge(int mfp, int edge); - /* * pxa3xx_mfp_config - configure the MFPR registers * -- 2.30.2
